“…Stronger interactions than simple dispersion forces have also been exploited to separate graphene from its substrate. Lock et al employed a diazonium-based adhesive to directly bind graphene sheets covalently, increasing the force that could be applied for separation of graphene from its substrate [91,92]. Seo et al used an amine-rich viscoelastic polyethyleneimine (PEI) polymer gel as a transfer layer to facilitate mechanical delamination.…”

Graphene, synthesized either epitaxially on silicon carbide or via chemical vapor deposition (CVD) on a transition metal, is gathering an increasing amount of interest from industrial and commercial ventures due to its remarkable electronic, mechanical, and thermal properties, as well as the ease with which it can be incorporated into devices. To exploit these superlative properties, it is generally necessary to transfer graphene from its conductive growth substrate to a more appropriate target substrate. In this review, we analyze the literature describing graphene transfer methods developed over the last decade. We present a simple physical model of the adhesion of graphene to its substrate, and we use this model to organize the various graphene transfer techniques by how they tackle the problem of modulating the adhesion energy between graphene and its substrate. We consider the challenges inherent in both delamination of graphene from its original substrate as well as relamination of graphene onto its target substrate, and we show how our simple model can rationalize various transfer strategies to mitigate these challenges and overcome the introduction of impurities and defects into the graphene. Our analysis of graphene transfer strategies concludes with a suggestion of possible future directions for the field.

“…The graphene sheet could be directly peeled off from the metal foil by using an adhesion film that provides strong adhesion forces, higher than the interaction between graphene and the metal substrate. The transferring agent could be as simple as thermal release tape (TRT), polymer [49] and hexagonal boron nitride [54] or could be as complex as introduction of organic linker [55] (figure 1) or heavy metal as adhesive [56]. For transfer printing, a simple polydimethylsiloxane (PDMS) film can be used as an adhesive tape to peel off the graphene [57].…”

Graphene is a two-dimensional material, a single layer of carbon atoms with a honeycomb lattice, which has increasing demand, especially wafer-scale graphene for applications in electronics industry. However, graphene requires to be supported on different substrates depending on its utilization and the transfer stage must be achieved without damaging the graphene structure. Wet chemical etching is the major route for graphene transfer widely applied right now; the loss of catalyst during the separation process being the main limitation. Mechanical peeling is a simple process but the quality of the separated graphene remains poor. Currently, electrochemical delamination or bubbling method and water assisted delamination are new and most promising methods for both efficient graphene transfer and possible catalyst reuse. This article provides a comprehensive review of the various graphene transfer methods without compromise in catalyst deterioration and it concludes with the future challenges in the domain.

For the first time, direct evidence of graphene-induced molecular reorientation in polymer films using polarization modulated infrared reflection absorption spectroscopy (PM-IRRAS) are presented. By creating favorable electrostatic interactions, graphene-polymer interfaces can be controlled by varying polymer and solvent composition. After trans of unmodified graphene from copper onto a polymer substrate, polymer chain rearrangement relative to the orientation at the polymer-copper interface is observed using PM-IRRAS. Transfer success is characterized using both optical transmission measurements and Raman spectroscopy to quantify the transfer fidelity, i.e. graphene coverage fraction. Taken together, oxygen-containing poly(ethylene-co-vinyl acetate)shows more polymer chain rearrangement and better graphene coverage compared to oxygen-free polyethylene. Polymer composition seems to dominate graphene-polymer interactions while solvent choice has a smaller effect on transfer quality. These results are the first direct measurement of this effect and point towards the possibility of engineering graphene-polymer interactions for specific applications.
